What is a Pyranometer Used to Measure? Understanding Solar Radiation Measurement
A pyranometer is used to measure global solar radiation. This instrument calculates the total solar energy—both direct and diffuse—reaching a horizontal surface, typically expressed in watts per square meter (W/m²). It plays a crucial role in meteorology, agriculture, and renewable energy systems.
How Pyranometers Work
Pyranometers operate using a thermopile sensor that detects temperature differences caused by solar radiation. The sensor generates a voltage proportional to the solar irradiance, ensuring accurate and reliable data collection for analysis.
Applications in Solar Energy
In solar power installations, pyranometers help optimize panel positioning and efficiency. By monitoring sunlight intensity, engineers can maximize energy output and improve system performance.
